Like HarleyCharlie says, no tool necessary to remove/install the bearing. Remove the snap ring and use a large socket or piece of PVC pipe the same OD as the bearing. Tap with a hammer and it will pop right out and back in with a little oil in the bearing boss.
Watch where you orient the snap ring when replacing so you don't block the hole for lubrication.
You should replace every seal in there while you are there; mainshaft seal and spacer, quad seal, mainshaft/5th gear seal, jackshaft seal and jackshaft thrust washer w/seal.
You will need a tool to hold the trans sprocket to R/R the inner race, or, you can remove the top cover from the trans and put the trans it two gears at once.

I bought an 80 dollar tool that will take care of the race. the bearing is the only tool need right now. I've removed bearings and installed them in the past using the hack cut method and the wack method , but since the inner primary has a failure rate of about 15K, a tool might be a good way to go. but it sounds like everyone is just wacking it out, then freezing the new bearing and heating up the primary case.

Don't forget the deep socket and "donut" you will need to R/R the trans pulley nut. If you have a 1/2" drive air wrench, that will usually break it loose but you will need a torque wrench to tighten.

If you don't have the parts manual, open the link, find your year and model and find the parts you need. IMHO, a parts manual is just as important as the service manual if one plans on working on ones bike.
